How easy is it to fit an SRM Powermeter ?

Its as easy as fitting a standard chainset. You do however need to make sure the magnet (which provide cadence and switches the powermeter on) is in the correct place. With so many different frame and bottom bracket dimensions this can be critical. We do however supply each powermeter with two magnets and a self adhesive pad for frames with internal cabling.
